_Serpula_ Linn. _Vermicularus De Montf. Vermet_ Adanson. The animal of the Serpulæ, it may be added further, does not differ, according to Cuvier, from those of the Linnæan Genus Turbo, and consequently not from Scalaria of Lamarck and Cuvier, as must be concluded from their admission of Turbo Clathratus among the number of its species, in an arrangement founded on the organization of the animal, as well as its testaceous habitation. Cuvier himself observes that the animal of the Vermet, and also the opening (of the shell) resemble those of the Turbo, but that the whorls do not touch, and are in part irregularly curved like the tubes of the Serpulas.—_Règne Animal T. 2. 419._ And his classification further shews the analogy of these tribes of shells, since the animal of the Linnæan _Turbo_, the _Vermets_ of Adanson, and _Scalaria_ of Lamarck, are all of the same family, the _Gastéropodas Pectinibranches_ of Cuvier. ------------------------------------------------------------------------ [Illustration: _27_ _London.
